Abstract

A three-way planar-type probe optimized for in-vivo permittivity measurements of biological materials has been developed. The probe in this letter consists of three orthogonally-faced probing apertures, which allows one to make accurate and uninterrupted measurements in three different directions per each insertion. As a result, this probe is significantly less invasive for the collection of the desired information of the biological materials, thus providing a vastly improved solution for in-vivo measurements. This probe can also be used for microwave ablation, in which case the treating region can be significantly expanded.
